A Jump That Should Not Kill You: Fixing a False Game Over in a Three.js Arcade Game

Short summary

A Three.js arcade game had a bug where pressing and immediately releasing jump triggered a false Game Over because the landing rule only checked for the next platform, ignoring the valid state of remaining on the origin platform. The fix adds a fallback collision check against the origin platform before declaring a miss, using a shared distance helper for consistent geometry. The article also discusses adding a cost to in-place hops to prevent exploit-free stalling.

• •Zero-charge jumps triggered false Game Over because landing logic only checked the target platform
• •Fix adds an origin-platform fallback check using a shared getLandingDistance helper for consistent collision rules
• •In-place hops remain recoverable but incur a streak reset cost to prevent exploitation
